ROCHESTER, N.Y., Jan. 12, 2009 – QED Technologies Inc. has released the Aspheric Stitching Interferometer (ASI) metrology system to measure steep aspheres.
The ASI measures aspheres with as much as 1000 waves of departure from the best fit sphere without the use of null lenses or computer-generated holograms, reducing the lead time for producing aspheres.
It is based on the company’s subaperture stitching technology and is complemented by its patent-pending Variable Optical Null technology, a programmable opto-mechanical subsystem that generates a wavefront closely matching the surface of the asphere subaperture being measured.
It takes high resolution subaperture measurements over the entire optical surface and the results are stitched together to form a full aperture map of the asphere being tested.
